TO ALL WHOM I'l MAY CONCERN:

Be it known that I, LUTHER M. SABIN, of the city and county of St. Louis, State of Missouri, have invented a new and useful Machine for Applying Water-Power; and that the following is a full und exact description of the same, reference being` had to the annexed drawing.

The nature of my invention consists in so constructing tivo pistons as to apply the hydraulic pressure to machinery.

Letter A is a'small vat, connected to the vat B by means of :L pipe, and furnished with an escape pipe, P. '.Lhis vat may be any distance from the lower one, B, and may be supplied with water by a hydraulic ram, or inany ordinary way. C C are cylinders, entering the vot B. E E ore pistons for said cylinders. M is a.

p cross-piece or lever, working on :i pivot. D Dl are bars to Work the valves with, and are furnished with shoulders where they enter the lever M so as to work the valves, and attached to the cross-bars O O', which Work in the upright pieces or standards. H H ure bars, fastened to crossburs O O und to the valves K K', and also underneath, to the vulves-F F', is a. bnr running from the cross-bars O O and fastened to them by pegs.

Now, let the vets be filled with water, and the piston E Will be driven outwhile the piston E will be driven in, the water being shut oli` the pistn E' by the valve K', and let to escape by the valve F being withdrawn from the orifice. At the same time the piston E is driven toits extremity; the valve K is shut down, Fis opened and K is opened and F is shut down, so the pressure ttets'on the piston Eso, vice versa. Machinery may be applied to the lever M or directly to the pistons E E'.

1. I claim the combination of vnt A and pipes, vat B, and cylinders C O', pistons E E', rods D D', lever M, valves F F and K K', and rods H H', as -ahove named and described, and for the purposes set forth.

2. I claim the combination of cylinders C C', pistons E E', bars D D and H H', valves F F and K K', and lever M. as above named and described, and for the purposes set forth.
